OpenAI's ChatGPT search feature has experienced significant growth in Europe, reaching approximately 41.3 million average monthly active users by the end of March 2025, up from 11.2 million six months earlier. This surge is part of OpenAI's compliance with the EU's Digital Services Act, which mandates transparency regarding user engagement. Despite its rapid rise, ChatGPT search still trails Google, which dominates the market with 373 times more searches. Concerns regarding the reliability of AI-powered search results persist, with studies indicating high rates of inaccuracies in content identification.
